Software Engineering - Fundamentals

Consider this simplified code snippet representing phases in a software process model:

phases = ['Requirements', 'Design', 'Implementation', 'Testing']
for i in range(len(phases)):
    print(phases[i])
    if i == 2:
        print('Review before Testing')

What will be the output?

ARequirements Design Implementation Testing Review before Testing

BReview before Testing Requirements Design Implementation Testing

CRequirements Design Review before Testing Implementation Testing

DRequirements Design Implementation Review before Testing Testing

Step-by-Step Solution

Solution:

Step 1: Understand the loop and conditions
The loop prints each phase in order. When index i is 2 (third item), it prints 'Review before Testing' before continuing.
Step 2: Trace the output line by line
Prints 'Requirements', 'Design', 'Implementation', then 'Review before Testing', then 'Testing'.
Final Answer:
Requirements Design Implementation Review before Testing Testing -> Option D
Quick Check:
Print phases in order + review at i=2 [OK]

Quick Trick: Print phases; add review after Implementation (index 2) [OK]

Common Mistakes:

Printing review after Testing instead of before
Mixing order of phases
Misunderstanding loop index
